@Beit known .that=1 GEORGE A. RAYMOND, a 'citizen-ofthe United States, `'residing Iat .Adriam ain fthe county of "Lenawee,- State of Michi-gan, :have IIinvented f certain new Vand v useful Improvements in Machines for Making WireFabricyandldo declare theffollowing tobea `full, clear, and exact description of the invention, lsuch as will enable others skilled invthelartto lwhich it appertainsto Inakeandusethe same, reference being had to-thevaccompanying drawings, and to the igures of referencemarked thereon, which form apart of this specification.

This-invention relates tolooms'for Weaving wireffabric, more especially designed 'for Ause inthemanufacture of wire fencing, the

general` character of-said loom being shown in my `copending application, Seriall No. 320, ll and the invention consists more particularly; inthe construction and operation of a duplex telescopic needle, whereby two strands of Woof-wires may be woven into the l ,fabric simultaneously and -a desirable cross- -anism. illustrated in Wrap accomplished, as -hereinafter more fully set forth, and pointed out particularly in the .-claims.

The object of the invention is'to provide efficient meansfor weaving the Woof-wires `vonto the ywarp-wires and making a cross wrap of the Woof-wires at the completion of each operation` of attaching said wires to the `warp-wires, the arrangement being such as to Y enable two warp-Wires to be applied simultaneously through the employment of la duplex: telescopic needle mountedin the shuttle and yactuated as the shuttle passes from strand to. strand of the warp-Wires in the operation ofweaving.

The above obj ect is attained by the mechy the accompanying draw-` ings, in which- Figure `11s a 4 .4 of Fig. 2. Fig. 5 is a detail,partly in sec- .f tion, ofthe duplex telescopic needle, the parts .thereof being disassembled. Fig. 6 isa frag- :mentaryviewinsection as on line. 6 6 of Fig.

The loom'or fence-.weaving machine, .of

which a portion only is shownl herein to illustrate the application of my invention, is of the rotary type and of the same general lconstruction as that shown anddescribedin my pending application, Serial No. 212,110.

The construction andfoperation thereof'Will not, therefore, bezspecifically entered into eX- l cept so far asmayl be necessary in describing the operation of my present invention.

Referring tothe characters o'ffreference, 1 designates the wheels,which, 'with the cross- Vplates 2 connecting them, form the yrotary shuttle .for each cross-plate and shuttlevtrack, the shuttles in succession'being carried across the longitudinal wiresas: the machine rotates. and `returned into positionfor a succeeding operation in a ymanner fullyset forth in my above-mentioned application. The shuttle is directed from wire to wireof `the longitudinal strands Vby means ofthe curved trackesections 7, which are :rigidly supported ina suitable manner (not shown) by t e framework .around the machine. .The

.movement of the vshuttle is made intermittent because ofthe divisions in the Vtrack 7, into engagement with which the antifrictionrollerS on the shuttle iscarried by the lrortary. movementof the machine, as partially illustrated inFig. 1.

The duplex needleA mountedine the. shuttle IOO comprises a telescopic shaft consisting of the male section 9 and the female section 10, fitting therein, said female section having a channel 11, which receives the pins 12 in the male section, whereby said parts are caused to register when placed together, so as to bring the longitudinal slots 13 therein in proper alinement and at the same time cause the sections to rotate in unison, while allowing them to reciprocate longitudinally. The

slotted needle formed by the telescopic sec-` \roller to engage the track member 19 the head15 will be moved between the guides, so as to throw the slotted needle into the notches 21 in the track members 3 along which the shuttle travels, causing said needle to receivein the longitudinal slot therein the war -strand 6 of the fabric which stands direct y over the notches in said trackjmemlbers, whereby the wire is embraced by the needle and causedto lie at the center of its vaxis of rotation, in which position the needle ii is rotated, as hereinafter explained, to wrap the warp or transverse wires around the line-wire, when by a further rotary movement of the main machine the roller 18 is caused to encounter the track-section 20,

i whereby the head 15 is moved outwardly and the yneedle withdrawn from the longitudinal wire, so as to enable the shuttle to move to the succeeding wire. i V

Upon the endsof the telescopic needle, as shown more clearly in Fig. 2, are the spools 22, which receive the coiled-wire bobbins 23, which form the transverse or Woof strands of the fabric and which by the travel of the shuttle and the rotation of the needle are wrapped ksuccessively abouty the warp-wires in the formation of the Woven fabric, said coiled cross-strands aying 0H of the spools from the needle as t ey are woven into the yfabric by the travel of the shuttle and the operation of the needle.

The needle isrotated to wrap the bobbinwires upon the longitudinal wires by means ofl a longitudinally-reciprocatory rack 24, which extends transversely of the machine and is pivotally connected, as shown at 2K5, to one end of a pitman 26, the opposite end of said pitman being attached to a crank 27 upon a shaft 28, carrying a pinion 29, adapted to mesh with a stationary rack 3Q. As the machine revolves said pinion is turned by engagement with said rack, imparting a rotary movement to the crank and reciprocating the rack 24, which in its movement in. one direction is in engagement with the slotted pinion 31 on the needle-shaft, causing the needle to rotate when embracing the longitudinal wire and lying in the notches 21 of the track members. AS the needle is retracted through the operation of the sliding head 15 it is raised or withdrawn from the notches, thereby carrying it from the longitudinal wire and removing its pinion from engagement with the rack 31, so that it will cease to rotate and that upon a movement of said rack it is not actuated. The forward movement of the rack-bar 24 occurs at the moment the needle embraces each of the linewires in succession and carries its pinion into contact with said bar.

To provide for a longitudinal reciprocation of the telescopic needle, there is mounted upon the female portion of the needle aslotted collar 32, within which the needle-shaft may rotate, but through which said shaft cannot move longitudinally. Extending from said collaris an arm 33, which stands parallel with the needle-shaft. In like manner a slotted collar 34 embraces the female portion 9 of the needle-shaft and is provided with the arm 35, which stands approximately parallel to the arm 33. In each of said arms is a pin 36, which is adapted to enter the slots 37 in the opposite faces of the collar 38, iixcd` to the shaft 39, whose outwardly-extending end carries a crank 40, provided at its free end with an antifriction-roller 41. It will be seen on referringto the dotted lines shown in Fig. 8 that a movement of said crank will rotate the collar 38 and actuate the arms 33 and 35, respectively, to impart a longitudinal movement to the male and female members of the needle, thereby elongating said needle, and that a movement of said crank in the opposite direction will contract the needle by causing the members thereof to slide together. This longitudinal reciprocation of the telescopic members of the needle is accomplished by means of the zigzag track 42, which is located in the path of the antifriction-roller 41 on the crank 40 and is so positioned as to engage said roller at the time the needle has made two revolutions around the line-wire and wrapped the transverse wire twice therearound, when by the elongation of said needle, due to the engagement of the roller of the crank in said zigzag track, will cause the third wrap to cross the other two, as shown at 43 in Fig. 7, thereby rendering the wrap or tie 44 perfectly secure and preventing it from becoming loose upon the longitudinal wire 6. There will be one of these zigzag tracks for each of the longitudinal or warp wires of the fabric, so that as the shuttle passes across the machine during the rotary movement thereof each of said tracks in succession will actuate the crank at the IOO lIO

' proper time to elongate the needle and cause the formation of the cross-wrap, as before explained. By this arrangement two of the transverse strands are simultaneously woven into the fabric during the passage of the shut# tle across the machine, and at each winding of the cross-wires' around the longitudinal wires the telescopic parts of the needle are actuated to form the cross-wrap 43, as illuse trated in Fig.r 7, producing in a rapid manner a woven fabric of superior quality.

At the initial point of operation as each shuttle enters upon its passage across vthe machine the ends of the transverse wires carried in the form of bobbins are fastened to the selvage of marginal wire of 4thexfabric by means of the rotary heads 45, which are mounted upon a common shaft and are operated by means of a reciprocatory rack 46 in a manner fully set forth in my application referred to above, and as such operation forms fno part of this invention it need not be further explained herein.

For the purpose of locking the rotary dupleX needle to hold itin the proper position when it is withdrawn from a lme-wire after )the operationof wrapping the cross-wires thereon a spring detent 47 is employed, which is mounted upon the hanger 14- and is provided with a hook-shape end, which normally engages in the teeth of the pinion 3l to hold said pinionfrom rotating. In order to free the pinion so as to permit the needle to revolve when it moves into position upon a longitudinal wire, said spring is caused to strike upon the track 3, so as to free it from engagement with said pinion, as clearly shown in Fig. 2.l

Havingthus fully set forth my invention, what I claim as new, and desire to secure by Letters Patent, is

Y cating said end portions, during the rotary 1.- In a machine for themanufacture of wire fabric, a longitudinally-slotted needle mounted to rotate, having longitudinally-reciprocal end portions, and means for recipromovement of theneedle.

and means for simultaneously sliding the secduring the rotary movement thereof.

In testimony whereof I sign this specification in the presence of-two witnesses.

GEORGE RAYMOND.
